Aldershot maintained their 100 per cent record with a hard-fought victory.
Striker Roscoe D'Sane secured the points with a coolly-taken 53rd-minute penalty after Mark Rogers was adjudged to have handled in the area.
Jon Challinor had the best chance of a disappointing first half when his close-range shot was pushed round the post by Borough keeper Robert Burch.
Stevenage pushed for an equaliser but Anthony Elding headed straight at Nikki Bull and Ritchie Hanlon fired wide.
